Specification of Letters Patent. Patented lvIay 1'7, 1910.

Application filed July 2, 1909, Serial No. 505,539. Renewed April 7, 1910. Serial No. 554,045.

To all whom it may concern:

Be it known that I, lVILLIAM J. BREWER, a subject of the King of England, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Roller- Bearings, of which the following is a specification.

The invention relates to im rovements in roller-bearings and is particu arly applicable to car-axle journals, which as ordinarily used are periodically subjected to excessive loads due to shock or vibration caused by the unevenness of the track or roadbed; and the object of the invention is to provide a bearing of the antifriction-roller type adapted to operatively receive the normal'working loads, and to further provide auxiliar supporting means acting through the ax e and rollers for receiving the incidental stresses due to shock or abnormal loading, to avoid excessive pressure upon the working parts.

A further object is to provide means for effectively lubricating such working parts; and the invention also includes certain details of construction hereinafter set forth.

In describing the invention in detail reference is had to the accompanying drawings,

.forming part of this specification, and wherein like characters of reference are used to designate like-parts throughoutthe several views, and in which:

' F igure 1 is a transverse view, partly in section, of the improved bearing embodying my invention; Fig. 2, a longitudinal view of the same, partially in section; and Fig. 3

is a detail view of the roller-retaining rings,-

a portion of one of said rings being in section. 1 p

The box or casing 1 is diametrically divided'in halves and interiorly provided with an annularbearing-ledge 2, having walls adapted to form a pair of semiannular recesses 8 and flanges 4, the latter receiving the bolts 5 for etachably connecting the half boxes together, the bolts being positioned within the recesses to preserve a regular exterior for the box. Secured 1n a convement manner to the bearing ledge 2, 1s a flanged wearing-sleeve or liner 6, en aged by the central journals or spindles 7 o a series of antifriction rollers 8, arranged in-"pairs on opposite sides of the bearing-ledge- The rollers engage thecentral axle or shaft 9,

and are retained in positive alinement with one another by the projecting spindles or .tribution being augmented Pockets or recesses 16 are formed in the bearing-surfaces to receive and distribute a suitable lubricant.

The retainer-rings are divided through a pair of opposite bearing-bars into two parts, and by the disconnection of the flange-bolts 5, the outer box or casing and the retainerrings with their. associated rollers may be readily removed without disturbing the Iposition of axle 9 or disconnecting the rol ers from the two-part retainer-rin s. The several parts may likewise be readily assembled and a suitable lubricant of graphite be in troduced, and by suitable clearances between the rollers and the annular bearing-ledge 2, the alinement of the retainer-rings together with their connected parts will be preserved in operative engagement within the casing.

The casing or box may be secured to the axle-frame (not shown) in any well-known manner, and the normal working-load transmitted thereto from the rotatable axle 9 throu the rollers 8 and the reduced journals g' 'to the stationary bearing-ledge 2, causing a relatively slow rolling movement of the two latter surfaces and a consequentreduction of wear. It will be evident that the rotation of the rollers will cause a relatively slow rotation of the retainer-rings and their connected bearing-bars about the axle which willelfect a distribution of the lubricant over the movable arts, such disy the pockets formed in said bearing-bars.

- When working under an abnormally excessive load tending to spring or strain any of the movable parts, the bearing-surfaces of the bearing-bars will temporarily engage the axle and transmit such load therethrough to the peripheral surface of the rollers, and

by reason of such additional bearing-surface will reduce the excessive stress upon the working contact-surface formed by theaxle, and the peripheriesof therollers, and will act as an auxiliary support for this relativel high rotating part. i

W at I claim as my invention and desire to secure by-Letters Patent, is:

1. In a roller-bearing, the combination with a box or casing rovided with an interior annular bearing-l mounted in the casing and'relatively 'rotatable thereto, roller-retainin rings disposed within said casing, hearing are Connecting said rings and adapted for incidental engagement with said shaft, a series of rollers loosely journaled' in the retainer-rings engaging said shaft and adapted for incidental engagement with the bearing-bars of said rings, and reduced journals formed on the of the bearing-bars, and reduced journals" formed onthe rollers for engagement, with rollers for engagement with said annular bearing-ledge. 1 a

2. In a roller-bearing, the combination with a box or casing provided with an interior annular bearing-ledge, an axle or shaft mounted in the casing and relatively rotatable thereto, roller-retainin rings disposed within said casing, bearinars connecting said rings and provided with recessed bearing-surfaces adaptedin part for incidental engagement with said shaft, a series of rollers' loosely journaled in the retainer-rings engaging said shaft and adapted for incidental engagement with the bearing-surfaces said annular bearingledge. v

3. In a roller-bearing, the combination with a box or casing provided with an interior annular bearing-ledge, of an axle or a shaft mounted-in the casing and relatively rotatable thereto, roller-retaining rings disposed within said casing, bearing-bars conedge, an axle or shaft necting said rings and adapted for inciden- I rollers secured to the spindles on opposite sides of the bearing-ledge engaging said shaft and adapted for incidental engagement with the bearing-bars of said rings.

4. In a roller-bearing, the combination with an axle,a two-part box or casing there for, an annular bearing-ledge formed within said casin and having exteriorly recessed 4 walls and ange-connection members, rollerretamm rings disposed within said casing,

bearingars connecting said rings andadapted for incidental engagement with said axle, a series of rollers journaled in the retainer-rings engaging said axle and adapted for incidental engagement with the bearingbars of said rings, and reduced journals in connection with the rollers for engagement with said annular bearingdedge.

5. In an axle-roller-bearing, a roller-re taining ring comprising two-side members and transversely connected bearing-bars, the latter adapted tocngage'the faces of the rollers and axle under excessive loads.

6. In an axle-roller-bearing, a roller-retaining ring comprising two side members and transversely connected bearing-bars, the latter having recessed bearing-faces adapted 'to engage the faces of the rollers and 'axle under excessive loads.
